QUOTATIONS

I walked my rented bicycle through the gate to the Boudhanath stupa, turned left, then rode clockwise around the massive white dome. A plastic bag of tangerines dangled from my handlebars, jerking as the bike bounced along the cobblestone road. The wide, circular path surrounding the shrine was an important kora: a devotional path, followed clockwise around a holy mountain or Buddhist monument. The ancient white dome of Boudha itself—symbolic of a lotus, an egg, and/or Buddha’s overturned begging bowl—rests upon a three-tiered plinth. The entire site, viewed from above, is revealed as a giant earthwork: an elaborate geometric mandala.

—JEFF GREENWALD, Snake Lake

The shapes of the letters are remarkably strong, written with expertise and confidence in symmetrical lines. Vertical strokes, both straight and rounded, are penned thickly with bold triangular pennant heads. Horizontal strokes are thin and are frequently used to join letters, sometimes with a slight triangular terminal.

—PETER BROWN, The Book of Kells

Mysticism always gripped the Welsh creative imagination, as we can see from the few Celtic artifacts still extant in the country. There is nothing straightforward to the manner of these objects, nothing right-angled or self-explanatory. They are neither realist in style nor entirely abstractionist—pictures which have evolved into patterns, triangles blurred into rhomboids, ritual combinations of curls and circles which may have some magic meaning, but have been stylized into an art form. When living creatures appear, they are caricature humans, schematic animals, and time and again there emerges the strange triskele, the wavy pattern of connected spirals which seems to have had some arcane fascination for the Celtic mind.

—JAN MORRIS, The Matter of Wales

“I used to play basketball,” he explained.

“You must’ve been pretty good.”

“I wasn’t bad, but all the shoes and balls are Cancer Perks.” He walked toward the TV, where a huge pile of DVDs and video games were arranged into a vague pyramid shape. He bent at the waist and snatched up V for Vendetta. “I was, like, the prototypical white Hoosier kid,” he said. “I was all about resurrecting the lost art of the midrange jumper, but then one day I was shooting free throws—just standing at the foul line at the North Central gym shooting from a rack of balls. All at once, I couldn’t figure out why I was methodically tossing a spherical object through a toroidal object. It seemed like the stupidest thing I could possibly be doing.”

Aulus recommended a mass-attack in diamond formation. The head of the diamond would consist of a single regiment in two waves, each wave eight men deep. Then would follow two regiments marching abreast, in the same formation as the leading one; then three regiments marching abreast. This would be the broadest part of the diamond and here the elephants would be disposed as a covering for each flank. Then would come two regiments, again, and then one. The cavalry and the rest of the infantry would be kept in reserve. Aulus explained that this diamond afforded a protection against charges from the flank; no attack could be made on the flank of the leading regiment without engaging the javelin-fire of the overlapping second line, nor on the second line without engaging the fire of the overlapping third.

Misha listened, but with a certain ethereal inattention. As I talked, he was twisting and folding a napkin into . . . something. He had lately become a master of origami, the Japanese art of paper folding. He had filled an entire room with his paper menagerie: octagons, tetrahedrons, storks, bugs.

The body of the machine was small, almost cylindrical, and pointed. Forward and aft on the pointed ends were two small petroleum engines for the screw, and the navigators sat deep in a canoe-like recess, the foremost one steering, and being protected by a low screen with two plate-glass windows, from the blinding rush of air. On either side a monstrous flat framework with a curved front border could be adjusted so as either to lie horizontally or to be tilted upward or down.

Weber tried a different approach when he included the subway in his 1915 painting Rush Hour: New York. Showing the height of the daily commute, it is a swirl of solid and transparent planes of color composed of irregularly shaped diamonds, hexagons, and semicircles that rotate around the canvas. The lower half of the composition is devoted to the underground spaces of urban transport with brown arches alluding to the underground tunnels of the subway.

When she’d stepped through to the other side, she turned and found that he was watching her from behind a glass wall. She went right up to it and pressed her face to it, near to his, so near that her eyelashes fluttered on the cold screen between them. He breathed on the glass and a nimbus of condensation billowed between them, and suddenly a fingertip was etching lines, curves, shapes into the mist. Letters.

The Russian defences consisted of a semi-elliptical-shaped fort containing 62 casemates on each of two floors from which heavy guns mounted in the centre could sweep the bay almost at water level. Behind the ellipse, and part of the fort, stood a large horseshoe-shaped work on two floors with casemates armed with heavy guns to flank the landward approaches. In the hills behind lay three round towers, also casemated, their guns commanding the countryside. All the masonry was granite, constructed in polygonal form similar to the method used by the Austrians at Verona.

When Hal comes in, Howard is standing at the counter, emptying a medicinal-looking powder into a fishbowl containing a single vermilion fish. The fish is shaped like the end of a shovel and has both eyes on one side of its head; the powder turns the water electric green. The vermilion shovel fish hovers meditatively in the electric green orb, like a bizarre Christmas ornament.

Volcanic islands generally are circular or elliptical cones or domes, and it is easy to visualize the influence of their shape upon erosion by imagining simple circular cones that lie in seas without waves and on which rain falls uniformly. The consequent rivers that develop on a cone are radial because the slopes of the cone are radial. The side slopes of the river valleys tend to be relatively constant but the longitudinal slopes are steeper in the headwaters than at the shoreline. Thus the valleys of the radial streams are funnel shaped; they are narrow and shallow at the shoreline and spread into great, deep amphitheaters in the interior.

The complex tangential and integer-ratio geometries found in most crop circles, even those of 1,000 feet in diameter, are awesomely accurate. The diatonic ratio (the white notes on the piano) has also been detected from triangle, square and hexagon ratios in certain formations, as have fractals and the Fibonacci sequence.

The great breakthrough, however, was in the development of the medieval Christian labyrinth design. This had eleven rings instead of seven, a characteristic cruciform design, and most significantly, the paths ranged freely through the quadrants, rather than methodically proceeding quarter by quarter in the Roman way. A manuscript in the Vatican dated AD860–2 contains a prototype of this innovatory medieval Christian design, and the tenth-century Montpellier manuscript portrays the design more formally. It was executed in two main forms, circular and octagonal.

—ADRIAN FISHER AND GEORG GERSTER, Labyrinth

A Vexierbild (puzzle-picture) by Schon, a Nuremberg engraver and pupil of Dürer, has been described by Rottinger: of large dimensions (0.44 metre × 0.75 metre) it is formed of four trapezoidal rows in which striped hatchings are continued by landscapes peopled with living figures. Towns and hills, men and animals are reabsorbed and engulfed in a tangle of lines, at first sight inexplicable. But by placing the eyes at the side and very close to the engraving one can see four superimposed heads inside rectilinear frames. Perspective causes the apparent images to disappear and at the same time the hidden outlines to appear.

The ball took place in the fair’s Natatorium, a large building on the Midway devoted to swimming and bathing and equipped with a ballroom and banquet rooms. Bunting of yellow and red hung from the ceiling. The galleries that overlooked the ballroom were outfitted with opera boxes for fair officials and socially prominent families. Burnham had a box, as did Davis and Higinbotham and of course the Palmers. The galleries also had seats and standing room for other paying guests. From railings in front of the boxes hung triangles of silk embroidered with gold arabesques, all glowing with the light of adjacent incandescent bulbs. Its effect was one of indescribable opulence.

If you draw a small irregular shape on the oblong edge of the pack, every tiny part of that picture will change when you shear the oblong to form a rhomboid. Only the area remains the same; and only the sides, which are straight and parallel, remain straight and parallel. But oceans and continents are not parallelograms!

Harald Alabaster’s study, or den, was next to Bredely’s small chapel. It was hexagonal in shape, with wood-panelled walls and two deep windows, carved in stone in the Perpendicular style: the ceiling too was carved stone, pale grey-gold in colour, a honey-comb of smaller hexagons.

If the long sides, given by joining the Station positions, were to be related to the Moon in the same way, the Station positions would need to form not a rectangle, but a parallelogram with corners that were not right angles. Shifting Stonehenge only 50 miles to the north or south would change the required angles by as much as 2°.

Fixed with cannons that could fire twenty miles, honeycombed with deep tunnels and lateral shafts, Corregidor was stuck like a steel bit in the mouth of Manila Bay.

Workers fabricated the javelin-like spire in pieces, lifted it into the tower, and riveted it together. A 30-ton crane stood ready. Van Alen waited for a perfectly calm morning. When it came, as the architect watched nervously from the street, the crane lifted the 28-ton needle into place. It took just 30 minutes. With that, Walter Chrysler’s skyscraper topped out at 1,048 feet, taller than the 986-foot Eiffel Tower, then the world’s tallest structure, and more important, taller than anything yet proposed by John Raskob.

These consist of cylindrical cells set together to form a palisade-like layer. . . . Each cell is polygonal in horizontal section; cuboidal cells are square in vertical section, whereas columnar cells are taller than their diameter. Commonly, microvilli are found on the free surface of such cells, providing a large, absorptive area . . . , as in the epithelium of the small intestine (columnar cells with a striated border), the gall bladder (columnar cells with a brush border) and the proximal and distal convoluted tubules of the kidney (large cells with brush borders).

Piet was by profession a builder, in love with snug right-angled things, and he had grown to love this house, its rectangular low rooms, its baseboards and chair rails molded and beaded by hand, the slender mullions of the windows whose older panes were flecked with oblong bubbles and tinged with lavender, the swept worn brick of the fireplace hearths like entryways into a sooty upward core of time, the attic he had lined with silver insulation paper so it seemed now a vaulted jewel box or an Aladdin’s cave, the solid freshly poured basement that had been a cellar floored with dirt when they had moved in five years ago. He loved how this house welcomed into itself in every season lemony flecked rhomboids of sun whose slow sliding revolved it with the day, like the cabin of a ship on a curving course.

Eucalyptus trees with their smoky, oily smell grew everywhere, very tall, the boles going far up before sending out a branch. They were untidy trees, with wood soft and weak. They kept losing branches, so that there were great gaps along the trunks. They kept dropping their narrow tan, spear-shaped leaves, which littered the ground under them, and layers of bark fell from them in long strips along with little wooden buttons, brown with crosses carved out of them on one side, powdery blue on the other.

Immediately on passing through Porta del Popolo the visitor enters a square, Piazza del Popolo. Today it is an oval but at that time it was a long, narrow trapezoid converging toward the gateway and with long garden walls on either side. Facing the city, one saw the three thoroughfares thrusting deep into the town. The two triangular building sites form an effective front with two symmetrical domed churches strongly emphasizing the solid mass of the houses advancing toward the open space of the piazza.

This monumental female saviour of his movement was to have carried a torch in one hand, lighting her kindly face, while the other would have supported a globe containing an entire theatre. Her robes would fall away to a great parade-ground where people could disport themselves in gentle diversions amid the scent of orange blossom. The basic idea is not new at all. As the mythographer Marina Warner notes, a Stone Age temple uncovered at Skara Brae on Orkney adopts the “cinquefoil form of a schematic female body, the entrance lies through the birth passage.”

On the computer-enhanced images they could see a patchwork of sinuous valleys like those found on Mars. There were also areas of grooved terrain, similar to that found by Voyager on the surface of one of Jupiter’s satellites, Ganymede. Elsewhere, the surface of Miranda resembled the cratered highlands of our own Moon, and there were also giant scarps higher than the Grand Canyon. In the centre of the satellite was a large rocky area shaped rather like a chevron, and two multi-ringed features rather like archery targets bracketed it.

It was an almost perfect cone of snow, simple in outline as if a child had drawn it, and impossible to classify as to size, height, or nearness. It was so radiant, so serenely poised, that he wondered for a moment if it were real at all. Then, while he gazed, a tiny puff clouded the edge of the pyramid, giving life to the vision before the faint rumble of the avalanche confirmed it.

Flora was ironing barefooted. Her habit of going without shoes in the house I found somewhat obscene because her feet were childishly shapeless and uncared-for. I thought of Nonie’s visits to her chiropodist to have her long, narrow feet soaked and sanded and the corns on the knobbly joints shaved away and her almond-shaped toenails blunt-cut and buffed to a high pink sheen, though nobody was going to see them but us.

There were always subtle differences, but for the most part, a lamb chop tended to maintain its basic shape. That is to say it looked choplike. It had a handle made of bone and a teardrop of meat hugged by a thin rind of fat. Apparently, though, that was too predictable. Order the modern lamb chop, and it’s likely to look no different than your companion’s order of shackled pompano.

First of all, when you consider the shape of a chickadee’s body, you will notice that it’s round. Whereas a blue jay is elongated, and a nuthatch tapered and slightly flattened, a chickadee is like a little ball. This roundness helps the small bird balance itself in the topsy-turvy positions it assumes while it’s searching for insect eggs on the twigs and outer branches of trees.

Marburg is one of family of viruses known as the filoviruses. Marburg was the first filovirus to be discovered. The word filovirus is Latin and means “thread virus.” The filoviruses look alike, as if they are sisters, and they resemble no other virus on earth. While most viruses are ball-shaped particles that look like peppercorns, the thread viruses have been compared to strands of tangled rope, to hair, to worms, to snakes. When they appear in a great flooding mess, as they so often do when they have destroyed a victim, they look like a tub of spaghetti that has been dumped on the floor. Marburg particles sometimes roll up into loops. The loops resemble Cheerios. Marburg is the only ring-shaped virus known.

If we look through a window at a mass of buildings, or any external objects, and observe that part of the glass to which each object, line, or point, appears opposite, we find that their apparent situation is very different from their real. We find that horizontal lines sometimes appear oblique, or even perpendicular, that circles, in certain situations, look like ellipses, and squares like trapezoids or parallelograms.

Two of the most famous, long landmarks of Manhattan are the Flatiron Building, erected in 1902, and the Times Building (recently remodeled as the Allied Chemical Building), in 1904. Both have odd, trapezoidal floor plans, dictated by the pie-shaped real-estate slices Broadway strews along its diagonal path as it crosses Manhattan avenues, Fifth at Twenty-third, site of the Flatiron, and Seventh at Forty-second, site of the Times. The resulting slenderness of the two buildings, plus the absence of scientific data on wind stresses, caused the New York engineers to take special precautions. Triangular “gusset plates” were inserted as braces, four to each joint of horizontal beam and vertical column.

Later, experimenting with small and full-size gliders, he found that setting the wings at a slight dihedral (or shallow V-shaped) angle to each other gave lateral stability, and that a tail plane set behind the main wings was necessary for longitudinal stability.

c. Ovoid or circular shape. This type of craft is described as being shaped like an ice cream cone, being rounded at the large end and tapering to a near-point at the other end. They are approximately 30–40 feet long and the thick end diameter is approximately 20 percent of the length. There is an extremely bright light at the pointed end, and this craft usually travels point down. They can appear to be any shape from round to cylindrical, depending upon the angle of observation. Often sightings of this type of craft are elliptical craft seen at an inclined angle or edge-on.

A geometric plan of Beaux-Arts derivation organized the main exhibit area into a rond-point system of radiating streets and fanlike segments. Symmetrical axes led to the Fair’s central theme building, the Trylon and Perisphere. The longitudinal central axis of Constitutional Mall extended from the Trylon and Perisphere eastward to the oval Lagoon of Nations and beyond, to the Court of Peace, which was flanked by foreign-sponsored pavilions and terminated by the symmetrical U.S. Government Building. Extending at 45º angles from either side of the Trylon and Perisphere were the Avenue of Patriots and the Avenue of Pioneers, both of which culminated in circular plazas—the former at Bowling Green, before the IRT and BMT entrances, and the latter at Lincoln Square.

The Old River Control Auxiliary Structure is a rank of seven towers, each buff with a white crown. They are vertical on the upstream side, and they slope toward the Atchafalaya. Therefore, they resemble flying buttresses facing the Mississippi. The towers are separated by six arciform gates, convex to the Mississippi, and hinged in trunnion blocks secured with steel to carom the force of the river into the core of the structure. Lifted by cables, these tainter gates, as they are called, are about as light and graceful as anything could be that has a composite weight of twenty-six hundred tons. Each of them is sixty-two feet wide.

In the evenings Mrs. Chaudhuri sometimes sang to them.

To bring light into the center of the room, a portion of the roof was raised about 4 meters higher than the roof over the side sections; the columns supporting the two sections differed, with bundle papyriform columns used at the side and full-blooming open papyriform columns in a larger size standing along the central aisle.

They were much shorter than any animal he had yet seen on Malacandra, and he gathered that they were bipeds, though the lower limbs were so thick and sausage-like that he hesitated to call them legs.

As long ago as 340 B.C. the Greek philosopher Aristotle, in his book On the Heavens, was able to put forward two good arguments for believing that the earth was a round sphere rather than a flat plate. First, he realized that eclipses of the moon were caused by the earth coming between the sun and the moon. The earth’s shadow on the moon was always round, which would be true only if the earth was spherical. If the earth had been a flat disk, the shadow would have been elongated and elliptical, unless the eclipse always occurred at a time when the sun was directly under the center of the disk.

Deep between two hills was an old quarry, which we were fond of pretending we had discovered. In places the stone stood in vertical shafts, six-sided or eight-sided, the height of stools or pillars. At the center of each of them was a sunburst, a few concentric circles, faint lines the color of rust. These we took to be the ruins of an ancient civilization. If we went up to the top of the quarry, we could ease ourselves a quarter of the way down its face on our toes along a diagonal cranny, till we came to a shallow cave, just deep enough for the two of us to sit in.

Fish scientists describe white sharks as traumatogenic to humans, meaning capable of causing an injury. The largest grow to nearly twenty feet and weigh five thousand pounds, about the same as a Lincoln Navigator. They are among the most modern looking of animals—eight fins on a tapered cylinder, a Bauhaus fish—yet their form is prehistoric. One woman told me that when she saw a white shark for the first time she felt as if she were seeing a dinosaur rising from the depths.

He reached the top of the hill; he turned a corner and the town was hidden. Down he looked into a deep valley with a dried up river bed at the bottom. This side and that was covered with small dilapidated houses that had broken stone verandahs where the fruit lay drying, tomato lanes in the garden, and from the gates to the doors a trellis of vines. The late sunlight, deep, golden, lay in the cup of the valley; there was a smell of charcoal in the air. In the gardens the men were cutting grapes. He watched a man standing in the greenish shade, raising up, holding a black cluster in one hand, taking the knife from his belt, cutting, laying the bunch in a flat boat-shaped basket.

Their discoverers may ambitiously have planned a concentric circle for which the eighty-two Q and R holes were intended, arranged in thirty-eight pairs with an additional six at the north-eastern entrance. But when the last bluestone was unearthed and the countryside scoured no more were to be found. In frustration, the scheme was modified into a less impressive single circle of about fifty-seven stones enclosing an elegant horseshoe of nineteen pillars. Even in the golden age of prehistory there could be blunders. Stonehenge was no exception.

Topology studies the properties that remain unchanged when shapes are deformed by twisting or stretching or squeezing. Whether a shape is square or round, large or small, is irrelevant in topology, because stretching can change those properties. Topologists ask whether a shape is connected, whether it has holes, whether it is knotted. They imagine surfaces not just in the one-, two-, and three-dimensional universes of Euclid, but in spaces of many dimensions, impossible to visualize. Topology is geometry on rubber sheets.

Under his eyes new cities grew. Mesa Verde, Aztec, Wupatki, Keet Seel. Each built and at the height of its prosperity abandoned until the people were gathered for their last great migration into the desert itself. Into four groups they divided themselves and in four directions they left, making a cross over the land until more hundreds of years passed and they wheeled right, forming a swastika. As this swastika wheeled, they broke into smaller groups, all returning but all moving in circles until the land was a giant’s pattern of moving swastikas and serpentines. A pueblo would live for an instant. Another group would find it and a spiral map of their predecessors’ path and then turn in the opposite direction, one eddy twisting from another, yet always directed to the finally permanent gathering at the center of the world.

In the jargon of his trade, this region was covered by “the semi-permanent Pacific High.” He looked at it malignantly. Then he smiled, for he noticed that the High had today accidentally assumed the shape of a gigantic dog’s head. Rising from the Pacific waters it looked out stupidly across the continent.

A small circle over southern Idaho supplied an eye; three concentric ovals pointing southwest from the California coast furnished a passable ear.

After dinner, I put clean towels on the bed in the guest room. My mother is sitting on the bed. The room has Harold’s minimalist look to it: the twin bed with plain white sheets and white blanket, polished wood floors, a bleached oakwood chair, and nothing on the slanted gray walls.

The only decoration is an odd-looking piece right next to the bed: an end table made out of a slab of unevenly cut marble and thin crisscrosses of black lacquer wood for the legs. My mother puts her handbag on the table and the cylindrical black vase on top starts to wobble. The freesias in the vase quiver.

On the prow of that stone ship in the centre of the strait, and seemingly a part of it, a shaped and geometrical outcrop of the naked rock, stood the pueblo of Malpais. Block above block, each story smaller than the one below, the tall houses rose like stepped and amputated pyramids into the blue sky. At their feet lay a straggle of low buildings, a criss-cross of walls; and on three sides the precipices fell sheer into the plain. A few columns of smoke mounted perpendicularly into the windless air and were lost.

But there were other objects of delight and interest claiming his instant attention; there were quaint twisted candlesticks in the shape of snakes, and a teapot fashioned like a china duck, out of whose open beak the tea was supposed to come. And there was a carved sandal-wood box packed tight with aromatic cotton-wool, and between the layers of cotton-wool were little brass figures, hump-necked bulls, and peacocks and goblins, delightful to see and to handle. Less promising in appearance was a large square book with plain black covers. . . .

I cut from a tree a score of long, blunt thorns, tough and black as whalebone, and drove them through a strip of wood in which I had burnt a row of holes to receive them, and made myself a comb, and combed out my long, tangled hair to improve my appearance.

“It is not the tangled condition of your hair,” persisted the voice, “but your eyes, so wild and strange in expression, that show the approach of madness.

In the bottom of their universe’s “bowl,” which we see in Figure 3.2 as a segment of a sphere, their straight lines are segments of great circles like the equator of the Earth or its lines of constant longitude.

Quite different from these nests of paper and clay are those of thickly felted vegetable hairs made by large wasps of the genus Apoica. Round or hexagonal in shape, five or six inches in diameter, these nests have the form of an umbrella without a handle or a stalkless mushroom.

It was in this place of astonishing miniatures that I came upon the lairs of the lions in the sunny sand—ant lions, that is. Small funnel-shaped pits dimpled the sand—inverted cones an inch or two in diameter across the top, tapering to the bottom perhaps an inch deep in the sand.

Later he stared at his finished work and longed to know if anyone other than Mr. Cromarty would be able to make sense of the miniature circles, dashes, and curlicues that floated freely above the lines with their sudden cruel hooks.

Particles may seem like a Platonic abstraction at first. They are fundamental and indivisible. They have no shape, size, color, or any other macroscopic properties. And any particle of a type will be completely identical and indistinguishable from one of the same type. Quite literally, if you’ve seen one electron, you’ve seen them all.

Probably the best known of the moths are the sphinx or hawk moths, some of which are so large they resemble hummingbirds. The bodies of these moths are relatively stout and torpedo-shaped.

But the ends of the “horseshoe” ran into the river which formed the northern boundary—and fourth side—of the plantation. And at the end nearer the house and outbuildings in the middle of the plantation, Leiningen had constructed a dam. By means of the dam, water from the river could be diverted into the ditch.

So, now, by opening the dam, he was able to fling an imposing wall of water, a huge quadrilateral with the river as its base, completely around the plantation, like the moat encircling a medieval city.

Colored red ochre, blue and tan, they paraded along the walls in that peculiar frontal way of Egyptians, with vultures on their palms, sheaves of wheat, water lilies and lutes. They were accompanied by lion, scarabs, owl, oxen and dismembered feet.

But being accepted one day doesn’t mean one will be welcome the next—the Jews of Buenos Aires couldn’t resist planning for dark times. So atop that modest wall they’d affixed another two meters of wrought-iron fence, each bar with a fleur-de-lis on its end. All those points and barbs four meters up gave that wall an unwelcoming, unclimbable, pants-ripping feel.

Kayerts stood still. He looked upwards; the fog rolled low over his head. He looked round like a man who has lost his way; and he saw a dark smudge, a cross-shaped stain, upon the shifting purity of the mist.

The room’s one window, too high for a woman not standing on a stool to peer out of, had lozenge panes of leaded glass, thick glass bubbled and warped like bottle bottoms.

But at first sight from the Derwent River—from which most museumgoers approach by ferry from downtown Hobart, the capital—MONA looms above like a post-apocalyptic fortress, waffled-concrete walls intersecting with great trapezoidal battlements clad in rusting steel.

The rich benignant cigar smoke eddied coolly down his throat; he puffed it out again in rings which breasted the air bravely for a moment; blue, circular—I shall try and get a word alone with Elizabeth to-night, he thought—then began to wobble into hour-glass shapes and taper away; odd shapes they take, he thought.

The world’s first ballistic missile was the Nazi’s V-2 rocket, designed by German scientists under the leadership of Wernher von Braun. As the first object to be launched above the Earth’s atmosphere, the bullet-shaped, large-finned V-2 (the “V” stands for Vergeltungswaffen, or “Vengeance Weapon”) inspired an entire generation of spaceship illustrations.

This miniature world demonstrated how everything was planned, people lived in these modern streamlined curvilinear buildings, each of them accommodating the population of a small town. . . .

Directly across the way stood a top-heavy dockhouse, a weatherbeaten cube of pure nineteenth century raised up on out-curving supports for the purpose of enabling elderly ladies to sit out on good afternoons to watch the sailboats leaning at their work—a setting rendered completely other-day and unreal by this thick, moist air.
